摘　　要：当气流流经山脉时,其流速和方向会产生一定变化,使得山地风场特性及其引起的风致效应更加复杂。为研究干扰效应对山脉地形风场的影响,文中选择规则山体形成的连续山脉地形进行风洞试验,对比研究山脉中各位置的风场特性。研究表明:山脉地形中山体之间的干扰效应会减小山顶的风加速效应,增大山脚、山坳和山腰的风减速效应;在风速沿高度变化过程中,这种干扰效应所引起的突变通常发生在测点与山顶之间的1/2高度处;山脉地形中山体的宽度、高度和山体间距对山体周边的风速分布均存在一定影响。The wind speed and direction will change to a certain extent when the wind flows through the mountain terrain,which makes the characteristics of mountain wind field and the wind-induced effect caused by it more complicated.To investigate the impact of interference effects on the wind field of mountainous regions,this research employs wind tunnel experiments using a continuous mountain terrain formed by regular mountains.The results show that the interference effect between mountains in mountain terrain will reduce the wind acceleration effect at the top of the mountain and increase the wind deceleration effect at the foot of the mountain,the depression and the mountainside.In the process of wind speed changing along the height,the mutation caused by this interference effect usually occurs at 1/2 height between the measuring point and the top of the mountain.The width,height and distance between mountains in mountain terrain play a crucial role in shaping the wind speed distribution in the vicinity of mountains.
